Experia xz screen lag/bug

Hello.

My xz is brand new, I've had it for three weeks now, never had accidents, falls or wet.

The touch screen seams to have some kind of issue, it's very difficult to swipe left the screensaver (it bounces back) also makes typing a nightmare, because it assumes that I'm swiping through letters, which I'm not. Lately I noticed that videos on instagram won't play.
